Before the enormous success of Silver Linings Playbook, both the book and the film, there was a young-adult novel called MonkeyShark.Don't expect a movie adaptation starring Bradley Cooper.But the poignant backstory of MonkeyShark and its protagonists - a redemptive tango of overcoming mental illness and miscommunication, surrendering old dreams and realizing new ones - would be a familiar plot to anyone who saw last year's Hollywood blockbuster starring Academy Award-winner Jennifer Lawrence.The book was a collaboration between Silver Linings' author, Matthew Quick, and his friend Evan Roskos. Just four years ago, they were two struggling South Jersey writers who met every Friday morning at a Collingswood coffee shop, working on their hoped-for bestseller.MonkeyShark would not be it.
